Middle School Textbook Work: Mathematics, Keirinkan Edition, Junior High School Mathematics, Year 2 Edited by Bunri Editorial Department This corresponds to the textbook "Mathematics Expanding into the Future, Year 2, Keirinkan." This is what I used in junior high school. Therefore, there are some creases here and there, but please consider it if you don't mind. Also, the answer key has been removed once, so there are some tears on the edges. (Photos 3 and 4) The appendices, "Speed Check Sheet, Red Sheet," "Key Point Summary Sheet," and "Study Cards" are in a removed state. Also, the study cards are in a created state, and the rings are not included, so they have been secured with zip ties. (Photos 5, 6, and 7) There are writings circling the page numbers in 3 places, but there are no other writings. (Photos 8, 9, and 10)
